Isolated from hyssop oil, it possesses antifungal, highly active whitening, and antioxidant properties, and it has potential applications in cosmeceutical materials. It downregulates proinflammatory cytokines in vitro and in vivo, reduces the number of total cells, neutrophils, and macrophages in BALF, attenuates histologic lung alterations, decreases the wet-to-dry weight ratio in BALF, and inhibits the activation of NF-kappa-B inhibitor alpha, extracellular regulated protein kinases, c-JunN-terminal kinase, and p38 mitogen-activated protein kinase.

Cefixime (FR-17027) is a broad-spectrum, third-generation cephalosporin antibiotic derived semisynthetically from the marine fungus Cephalosporium acremonium with antibacterial activity. As does penicillin, the beta-lactam antibiotic cefixime inhibits bacterial cell wall synthesis by disrupting peptidoglycan synthesis, resulting in a reduction in bacterial cell wall stability and bacterial cell lysis. Stable in the presence of a variety of beta-lactamases, this agent is more active against gram-negative bacteria and less active against gram-positive bacteria compared to second-generation cephalosporins.

Tucidinostat (Chidamide) is an effective and orally bioavailable HDAC enzymes class I (HDAC1 2 3) and class IIb (HDAC10) inhibitor, with IC50s of 95, 160, 67 and 78 nM, less active on HDAC8 11 (IC50: 733 432 nM), and shows no effect on HDAC4 5 6 7 9.

AT7519 is a CDK1 2 4 6 9 inhibitor (IC50: 10-210 nM). It is less effective to CDK3 and little active to CDK7.

(R)-Q-VD-OPh is the less active enantiomer of Q-VD-OPha. Q-VD-OPha is an irreversible inhibitor of pan-caspase, with potent antiapoptotic properties.

Mefentrifluconazole is a potent, selective and orally active fungal CYP51 (Kd= 0.5 nM) inhibitor, but shows less inhibitory activity on human aromatase (IC50=0.92 μM). Mefentrifluconazole is a novel azole derivative and used as an agrochemical broad-spectrum antifungal agent.

ARS-1630 is a mutant K-ras G12C inhibitor. It is a less active enantiomer of ARS-1620.

AS-041164 is a selective and orally active PI3Kγ isoform inhibitor(IC50 of 70 nM), and shows less activity against PI3Kα, PI3Kβ, and PI3Kδ (IC50s of 240 nM, 1.45 μM, and 1.70 μM, respectively). It has anti-inflammatory effects.

GSK9027 (GR agonist 23a) is a nonsteroidal glucocorticoid receptor (GR) agonist.GSK9027 is a partial agonist on the 2×GRE reporter gene compared to dexamethasone and is less active than dexamethasone activity.

Tyrphostin B44, (+) enantiomer is an inhibitor of epidermal growth factor receptor (EGFR) kinase with IC50 of 0.86 μM and has less active than the (-) enantiomer.

SAR405 (R enantiomer) is the less active form of SAR405, an inhibitor of PIK3C3 Vps34.

Cerdulatinib hydrochloride (PRT2070 hydrochloride) is an oral active, multi-targeted tyrosine kinase inhibitor with IC50 of 12 nM 6 nM 8 nM 0.5 nM and 32 nM for JAK1 JAK2 JAK3 TYK2 and Syk, respectively. Also inhibits 19 other tested kinases with IC50 less than 200 nM.
